Radiator



Feb. 17, 1931. A. ROBITAILLE RADIATOR Filed Jan. 28, 1929 Patented Feb. 17, 193 1 UNITED STATES LOUIS ARTHUR ROBITAILLE, or MONTREAL, QUEB C, CANADA RADIATOR Application filed January 28, 1929, Serial No. 335,603, and in Canada June 9, 1928.

The invention relates to a radiator, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

novel features of construction pointed out broadly and specifically inthe claims for novelty following a description containing an explanation in detail of an acceptable form 0 of the invention.

The objects of the invention are to reduce the consumption of hard soft or liquid fuel or of electric current used in heating systerns by increasing the area of the heating surfaces and minimizing the thickness of the sheet of water, or steam flowing through the radiator; to lighten theconstruction of radiators, whereby the contractor or builder will be able to install them in any suitable position on the walls or other structuralparts to market the radiators at a reasonable price to the consumer and at the same time insure a good profit to the manufacturer; and gen erally to provide a light weight radiator of durable nature and efficient in its operation.

In the drawings, Figure 1 is a front elevational view of the radiator complete.

Figure 2 is a rear elevational view of the radiator complete.

Figure 3 is a plan view of the radiator showing the tie rod in position. 7

Figure 4 is a cross sectional View on the line H in Figure 1. g

Figure 5 is an end elevational View of the radiator.

Figure 6 is a vertical sectional view, showing the bracket and hangers for securing the radiator to the wall.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, this invention is formed of two sheets of metal spaced from one another and welded at the ends.

These sheets indicated by the numerals 10 and 11 are formed in the curves 12 and the reversed curves 13 representing a plurality of S shapes, terminating at the ends in the vertical tubes 14 and 15.

The several 8 shapes may be said to begin at the contacting walls 16and 17 throughout The invention consists essentially of the the'length of the radiator, while the contact 'ing walls 18 and 19 may be said to be intermediate of the S shapes and represent the abutments' of forward andreverse curves in the length of the radiator, the same as the abutments at the beginning of the S shapes,

namely the contact walls 16 and 17 y The various S. shapes are held together by the tie rod 20, which is formed with the end flanges 21 and 22 inserted in the recesses 23 and 24 made by the formation of the tubes 14 and 15. V

, The flanges 21 and 22 are welded on to the sheets, while the sheets themselves are welded together at the top and bottom'ends and these hangers areinserted in slotted wall brackets indicated by the numeral 33.

The top 34 is secured in any suitable way on the coiled sheet and closes in the tie rod 20.

In the operation of this radiator in hot" water heating systems, the water is fed in through the nipple 27 and distributes itself throughout the whole length of the radiator, naturally the radiator is kept reasonably full of water,rso that as it flows in its circulation throughto the return nipple 29, it heats the two surfaces of sheet metal throughout, thereby heating the apartment" or room in which the radiator is contained.

What I claim as my invention is 1. A radiator comprising a plurality of' sheets of metal spaced from one another and drawn together at the top and at the bot tom and welded, and at the ends welded together and forming at said ends tubular passages having an inlet and outlet respective 1y, said passages communicating from top.

to bottom with the interior of the radiator casing throughout, nipples in said inlet and outlet respectively, and a tie rod having flanged ends and engaging said radiator in recesses made by the formation of said tubular ends, and drawing the curved portions of .the casing throughout the length into proximity and holding them in that position.

2. In a radiator, a casing formed of a plurality of metal sheets of curled S shaped portions in a continuous length beginning at a communicating vertical tubular passage and terminating in a communicating vertical tubular passage and forming by said tubular passages in the outer Wall or" the casing acute angle recesses, a tie rod formed to fit in said recesses and extending along the upper ends of the curled port-ions and having flanges secured to the casings at the ends in said recesses and itself secured intermediately, and a top mounted over said tie rod and suitably secured to the radiator casing.

Signed at Montreal, Canada, this 11th day of September, 1928.
